The tundra is one of the last wild frontiers of the Earth. It stretches across regions such as Alaska, Canada, Finland, and Russia, and includes three main types: Arctic tundra, alpine tundra, and Antarctic tundra. These ecosystems are home to some of the most resilient wildlife, such as arctic foxes, caribou and snow geese, which have adapted to withstand harsh conditions where temperatures drop dramatically and growing seasons are fleeting. But this delicate balance is under threat—and not just from humans. The twin forces of climate change and rising methane emissions are putting unprecedented pressure on tundra ecosystems, affecting the wildlife that depends on them. This is not just an environmental problem – it is a global problem that requires urgent attention. Why tundra wildlife is under threat 1. Thawing of permafrost and release of methane A significant threat to the tundra is the melting of permafrost. The tundra is a huge carbon sink, storing vast amounts of carbon in froz...

The space industry is developing at a rapid pace. As commercial spaceflight, satellite launches, and even research missions proliferate, the need for coordinated space traffic management increases.

Tutoring centers that focus on science, like the one at Scottsdale Community College (SCC), are indispensable for students who struggle to grasp complex concepts. These centers offer a collaborative environment where students can ask questions and receive personalized guidance...

Hurricanes are nature's strongest reminder of the immense power of our planet. However, despite the destruction, they seem to have failed to teach humanity a lasting lesson. As climate change continues to worsen, you'd think these storms would inspire a deeper awareness of our fragile relationship with the Earth. Unfortunately, the opposite appears to be the case, and humanity remains largely indifferent to the urgent need to combat climate change. Take, for example, Hurricane Helen, which recently devastated North Carolina, leaving a trail of destruction in its wake. At least 30 have been confirmed dead, with dozens missing in Buncombe County alone. Despite the catastrophic flooding and severe damage, the question remains: what have we not learned? Hurricanes and Climate Change: The Inevitable Link One of the key issues with hurricanes is their increasing intensity, which is closely related to climate change. Warmer sea temperatures are causing stronger and more destructive st...

As a pet owner and animal enthusiast, I have always believed that every animal deserves a safe home. Unfortunately, the problem of stray animals continues to grow in urban areas around the world, bringing with it numerous problems, including public health risks due to zoonotic diseases. However, the solution may be simpler than we think: mandatory microchipping of pets. The homeless animal crisis in numbers The number of stray animals in big cities is amazing. In the US alone, an estimated 6.5 million animals enter shelters each year, and only a small fraction are returned to their owners. This is not just a local problem; All over the world, tens of millions of stray dogs and cats roam the streets. Uncontrolled breeding and lack of identification are the main causes of this problem, resulting in overcrowded shelters and millions of dollars spent on managing the stray population. How microchipping can solve the problem Microchipping provides a permanent method of identification that li...

When we think about the future of our planet, one of the most important components is how we manage and predict changes in our oceans. The success of new projects, especially in the field of oceanology, is not just a goal, but a necessity. In regions like Japan, the Americas and Argentina, where coastal communities are vulnerable to everything from sea level rise to ecosystem change, ocean forecasting projects play a key role in protecting lives, industries and ecosystems.

Why ocean forecasting is critical From Argentina's f...

For centuries, the Egyptian pyramids have been a source of fear, fascination and intrigue. Their grandeur and precision have inspired countless theories about their construction, some based on history and science, while others lean toward the extraordinary and fantastical. But why, in an age of scientific progress, do some still believe in more outlandish explanations, such as aliens or lost civilizations such as Atlantis? As someone who enjoys exploring human beliefs and how they shape our understanding of history, I find the persistence of these myths quite fascinating. Many people, faced with the greatness of the pyramids, try to understand how ancient civilizations could achieve such feats. This disbelief often gives rise to myths—stories of extraterrestrial intervention or lost superhuman civilizations. Who actually built the pyramids? The scientific and archaeological consensus is clear: the pyramids were built by skilled Egyptian workers, not by aliens or the inhabitants of the ...

In a fast-paced world, the intersection of health and safety is becoming increasingly vital. Chile's proposed 2025 budget, with a 2.7% increase in spending and a focus on fighting organized crime, underscores the importance of security in building a healthy society. While the immediate focus is on crime prevention, there is growing recognition that health and safety are interrelated. As Chile strengthens its borders and law enforcement, it lays the foundation for public health. But this raises an important question: How do investments in security contribute to better health outcomes, and what can other countries learn from Chile's example? The health and safety nexus At first glance, health and safety may seem like different fields. However, they are more connected than we often realize. A safe environment is a prerequisite for a healthy society. Here's why: Crime prevention reduces health risks: Organized crime, particularly drug trafficking, often leads to violence, addic...

In a world increasingly aware of environmental crises, the Middle East remains an arena for another form of devastation: merciless war. The failure of major world powers such as the United States, Russia and China to stop these conflicts is not only a matter of politics or diplomacy. It is a reflection of deeper systemic problems, including the environmental degradation that accompanies and exacerbates war. Why can't the major countries stop the war in the Middle East and how does this relate to the environment? Key factors undermining global efforts to end conflict Declining US influence Over the past few decades, the United States, once considered a dominant force capable of changing global dynamics, has seen its influence in the Middle East diminish. Shifting alliances, complicated local politics, and rising anti-American sentiment have reduced his ability to deliver results. Environmental destruction caused by military operations further alienates the local population, reducing...

The story of the northern elephant seal is a story of incredible survival. These huge marine mammals were once nearly driven to extinction by relentless hunting in the early 20th century. Today, however, their population has recovered to over 225,000 individuals thanks to conservation efforts. But what does this resurgence mean for their genetic diversity and long-term survival? Recent research, including ground-breaking research published in Nature Ecology and Evolution, is revealing a critical understanding of the genetic challenges these animals face as they near extinction. The near extinction of northern elephant seals At the beginning of the 20th century, the population of northern elephant seals (Mirounga angustirostris) declined to less than 25 individuals. Intensive hunting for their blubber, which is prized for oil production, almost wiped out the species. With only a handful of survivors remaining, the species' genetic pool has been drastically reduced. This extreme popu...

SpaceX launched an extraordinary mission to rescue two NASA astronauts stranded on the International Space Station (ISS). Originally scheduled to return earlier this year, the astronauts will now remain in space until February 2025, marking one of the longest unplanned stays in ISS history.

The results showed that children conceived using a...

In a bold and unprecedented move, Pope Francis has once again taken a stand on one of the world's most pressing issues: climate change. This time, however, the pontiff also pointed the finger at the Catholic Church itself, calling out what he called the "shameful abuse of the climate" and acknowledging the Church's responsibility in these matters. His remarks, made in the wake of recent revelations about the Church's complicity in Belgium's environmental and ethical failings, have sparked widespread debate and self-reflection in religious communities. The Church and responsibility for the climate Pope Francis has long been actively advocating the fight against the climate. His 2015 encyclical Laudato Si' called for global efforts to combat environmental degradation, but now the Pope's words carry even more weight. By using the term "shameful", Pope Francis emphasizes the moral inability of the Church, especially in Belgium, to solve climate p...

The environment plays a more significant role in our overall health than we often realize. Beyond the obvious factors such as air quality, pollution and climate, our well-being is deeply affected by more abstract elements such as the social, cultural, psychological and financial environment. September 26 is World Environment Day, which reminds us that environmental health encompasses more than just clean air or water—it affects every aspect of our daily lives. Organized by the International Federation for Environmental Protection (IFEH), the day aims to raise global awareness of these interrelated issues. Broader definition of environment Traditionally, the term "environment" refers to the physical environment—land, water, air, and natural resources. But modern research shows that environmental health is much broader. It includes the psychological, social and cultural contexts in which we live. These abstract aspects are as critical to human development and health as the phys...
